WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• Use safety shoes with a metal toe cap. Use protective gloves.
• Use protective eyewear when working with the liquid cooling system.
• Handle the converter modules carefully:
• Lift the module with a lifting device only. Use the designated lifting points.
See the lifting instructions.
• Do not tilt the module. It will overturn very easily because it is heavy and its
center of gravity is high.
• Modules running on wheels: Make sure that the module does not topple over
when you move it on the floor: Whenever possible secure the module also
with chains. Do not leave the module unattended on a sloping floor.
• Beware of hot surfaces. Some parts, such as heatsinks of power
semiconductors, remain hot for a while after disconnection of the electrical
supply.
• Keep the converter in its package or protect it otherwise from dust and burr
from drilling and grinding until you install it. Protect also the installed converter
against dust and burr. Electrically conductive debris inside the drive can cause
damage or malfunction.
• Vacuum clean the area below the converter before the start-up to prevent the
converter cooling fans from drawing the dust inside the converter.
• Do not cover the air inlet and outlet when the converter is running.
• Make sure that there is sufficient cooling. Before power switch-on, make sure
that the liquid cooling circuit is filled up with coolant. Running the external cooling
pump dry will damage it. Also the converter will not cool down. See the converter
hardware manual.
• Before you connect voltage to the converter, make sure that the cabinet doors
are closed. Keep the doors closed during operation.
• Before you adjust the converter operation limits, make sure that the generator
and all driven equipment can operate throughout the set operation limits.
• The maximum number of converter power-ups is five in ten minutes. Too
frequent power-ups can damage the charging circuit of the DC capacitors.
• Make sure that safety circuits (for example, emergency stop, if any) are validated
at start-up.
• Beware of the cooling fan blades. The fans can continue to rotate for a while
after the disconnection of the electrical supply.
• Service the main circuit breaker once a year. If not serviced, damage can occur
to the wind turbine.
Note:
• Only authorized persons are allowed to repair a malfunctioning converter.
